Due to the load imbalance, current flows in the neutral of the transformer. The current flowing in the neutral conductor of this transformer causes an imbalance in the transformer load, losses, namely losses due to the neutral current in the transformer neutral conductor. The losses contained in the transformer are power loss, core loss and copper loss. In analyzing the problem using a mathematical model includes the transformer load imbalance equation, power losses and efficiency. After being analyzed, it shows that the transformer is in an unbalanced state where if there is a large load imbalance, the neutral current that appears is also large. The efficiency of the transformer will be even greater if the difference between incoming and outgoing power is small. The percentage of loading on Transformer one is 22.5% and Transformer two is 5.14. The load imbalance is bigger at night, that is, Transformer one is 187% and Transformer two is 2.66%.} }
